Just couldn't find help with this anywhere but
Using the desmos graphing calculator using the table feature
I wanted to plot the points every $\frac{\pi}{12}$
$0<\theta<2\pi$
For $r=-2-3\sin(\theta)$

On a polar coordinate graph

Hi karush,

It seems that Desmos doesn't allow directly inserting $r$ and $\theta$ values to its table feature. A way around this is to get the relavant $x$ and $y$ coordinates using something like Google Sheets and then copy these values to Desmos. This way you can get the plot you need. Here is what I came up with.
